This would be nice. It really makes sense because right now there is no place for countrymen to go over tactics and other things in private.
As far as passwords are concerned, I think If you were with a country for 1 entire tour, you receive the password for the next tour. The password could reset every tour as to discourage country jumpers from leaking information.
Maybe worth a try.
